MarkItDown: Microsoft’s open-source tool for Markdown conversion

Microsoft has introduced MarkItDown, an open-source Python utility that converts various file formats into Markdown. The tool is designed to help with fine-tuning large language models (LLMs) and building retrieval-augmented generation (RAG) systems. MarkItDown preserves document structures, supports multi-modal data like images and audio files, and integrates with LLMs for enhanced functionality. Despite some limitations, it addresses key challenges in document processing and offers a modular and extensible architecture for developers.
